From what I remember BladeTech is very different, and it's a very much a either you love it or hate it type of deal.
My kid uses non-DLC JRZ as a 2nd set and it seems to hold up well compared to his stock.
I got my spare blades lightly used from SLS for a great price, if you are patient, maybe you could find yours there. What size are you anyway? I have a couple of Size 9/280 that I might be selling.
